In the C# stub, base is a keyword and can't be used as a variable.

C++: No need for floats

int main() {
    uint32_t a, b;
    cin >> b >> a;
    cout << 2 * a / b + bool((2 * a) % b);   
    return 0;
}

C in one line

int lowestTriangle(int base, int area){
    
    return ceil((float)(2*area)/base);
}

I am so mad. One of the test cases' answer was 2000000 and C++ std::cout gave the output as 2e+06 instead of 2000000 so it gave a wrong answer... I really need to start using std::printf everywhere.

Python oneliner:

import math;print(int(list(map(lambda x: math.ceil(2*x[1]/x[0]), [[int(i) for i in input().strip().split(' ')]]))[0]))

include

int main() { int i,b,a,h,a1;

    scanf("%d %d",&b,&a);
    h=2*a/b;
    a1=b*h/2;
    if(a1==a){


    printf("%d",h);
    }
    else
    {

    printf("%d",h+1);
    }

    printf("\n");
return 0;

}

int main() { int base; long int area; cin >> base >> area; long int m= ceil((float)(2*area)/base); cout<< m;

return 0;

}

python2

def lowestTriangle(base, area):
    x = area*2
    ans = int(x/base)
    return ans if x % base == 0 else ans + 1

GoLang fmt.Printf("%.0f\n", math.Ceil((2.0*a)/b))

Using common lisp:

(defun height()
    (let ((b (read))
          (a (read)))
         (format t "~A~%" (ceiling (/ (* 2 a) b)))))

(height)
